this deserves a thread of its own. you can now downgrade a 2.5 or 6 psp .... well theres still a really small risk of bricking it and its still in beta and if it says ta 82 under the umd drive then it will brick your psp. still if you have any other psp apart from a ta 82 ones the success rate is nearly 100% i cant wait to dwngrade my 2.5 when i get my psp back tomorrow (stupid parents didnt pick it up when i told them to)
